Which of the following salts undergo exclusively anionic hydrolysis when dissolved in an aqueous med — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

Anionic hydrolysis occurs in salts formed from a weak acid and a strong base. The strong base cation ($K^+$, $Na^+$) merely hydrates, while the weak acid anion ($CN^-$, $CO_3^{2-}$, $CH_3COO^-$) reacts with water to form the weak acid and release $OH^-$ ions, making the solution basic. $NH_4Cl$ undergoes cationic hydrolysis.
